POWER INVERTER
300 W KH 3900
Intended Use
The device is intended for connection to a 12 V in
vehicle receptacle or an automotive battery and for
220 - 240 V AC output for connection of electrical
devices with a power consumption up to 300 W.
The device is not intended for commercial or industrial
purposes.
No guarantee claims will be granted for damage
resulting from improper use!
* Pay attention to the information regarding
current usage and power consumption on
the rating plate of the device you intend to
operate.
Before operation make sure that the maximum
power consumption does not exceed 1,3 A
and the maximum continuous load is not
more than 300 W.
Attention!
Sensitive electronic devices should not be opera-
ted with the power inverter since the output vol-
tage is not sufficiently constant for these devices.

Safety information
• This device is not intended for use by individuals
(including children) with restricted physical, physio-
logical or intellectual abilities or deficiences in
experience and/or knowledge unless they are
supervised by a person responsible for their safety
or receive from this person instruction in how the
device is to be used. Children should be supervised
to ensure that they do not play with the device.
• To avoid dangers remove the power inverter
from the vehicle receptacle and/or the connec-
tion terminals from the automotive battery after
each use and before every cleaning.
• Only connect the power inverter to the automotive
battery when the engine is switched off! The
possibility of injury exists from rotating parts!
• Check the device and all parts for visible damage.
The safety concept of the device can only function
properly when it is in perfect condition.
• The power inverter must always be easily accessible
so that, in case of emergency, it can be quickly
disconnected from the power supply system.
Risk of electrical shocks.
• Connect the power inverter only to a 12 V auto-
motive battery/vehicle receptacle. Connecting
the device to a 24 V supply could damage it.
• When connecting the power inverter via the 12 V
vehicle plug make sure that the polarity of the
vehicle plug matches the polarity of the in vehicle
receptacle. The vehicle socket must have an inter-
nal positive pole, that is to say that the positive pole
of a vehicle battery cannot be connected to the
chassis of the vehicle.
• Check before connecting the power inverter that
the vehicle receptacle is sufficiently secured. This
safeguard may not in any way be circumvented
or changed.
